Quality of life in bladder cancer: systematic review and meta-analysis.	BACKGROUND: Worldwide, bladder cancer (BC) has been regarded as the tenth most common cancer with more than 573 000 new cases in 2020. This research presents a systematic review and meta-analysis of studies examining the quality of life (QOL) among patients with BC. METHODS: The study was designed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A total of 11 articles were extracted from a literature search conducted through electronic databases including PubMed, EMBASE, Scopus and Web of Science from the onset of January 2000 to June 2022. A random-effects model was applied to estimate the pooled QOL in patients with BC. RESULTS: We included 11 primary studies in the final meta-analysis. Based on random effect analysis, total score of QOL was 53.92 (95% CI: 47.84 to 60) representing a moderate level of QOL among patients. Based on the analysis, it was found that physical items with a score of 49.82 (95% CI: 45.8 to 53.84) had a lower score in comparison with mental items at a score of 52 (95% CI: 49.54 to 54.47). In addition, the item of role limitations due to physical health with a score of 46.26 (95% CI: 20.11 to 72.41), and social functioning with a score of 46.25 (95% CI: 18.85 to 73.66), respectively, had the lowest QOL in patients with BC. CONCLUSION: Generally, the QOL among patients with BC was in a moderate condition, which can be improved through determining the influencing factors on QOL as a crucial strategy to define future treatment procedures in an effective manner.	bladder
Bladder-sparing strategies in patients with clinically localized muscle-invasive bladder cancer.	PURPOSE OF REVIEW: Radical cystectomy is the standard of care for patients with localized muscle-invasive bladder cancer (MIBC). In this context, bladder-sparing strategies (BSS) have been investigated as viable alternatives for patients who are unfit for radical cystectomy or aim to preserve their bladder without compromising oncological outcomes. This review aims to provide the most up-to-date evidence on BSSs as an alternative treatment for patients with MIBC. RECENT FINDINGS: Different studies have highlighted the long-term efficacy of trimodal therapy or chemoradiation protocols. However, due to the lack of randomized controlled trials, there is still a lack of high-level evidence on BSS efficacy as compared to radical cystectomy. Consequently, the adoption of these approaches is still limited. A possible turning point could be represented by the introduction of immunotherapy, as several studies are investigating the potential combination with chemoradiotherapy or radiotherapy alone. Patient selection, together with the implementation of new predictive biomarkers and imaging tools, may improve the efficacy of BSS in the near future. SUMMARY: Radical cystectomy with perioperative chemotherapy remains the gold standard treatment for MIBC patients. Nevertheless, BSS can be considered a viable option in selected patients who desire to preserve their bladder. Further evidence is needed to clearly state the role of BSS in MIBC.	bladder
LncRNA PVT1 promotes bladder cancer progression by forming a positive feedback loop with STAT5B.	BACKGROUND: Plasmacytoma Variant Translocation 1 (LncRNA PVT1) and signal transducer and activator of transcription 5B (STAT5B) play important roles in various cancers, but their interaction in bladder cancer (BC) remains unclear. PURPOSE: We aimed to explore the interaction between lncRNA PVT1 and STAT5B in BC tumorigenesis and find potential drugs for BC. METHODS: The association of the expression of lncRNA PVT1 and STAT5B to the prognosis of BC patients was evaluated via bioinformatic analysis. Loss- and gain-of-function assays were performed to determine the biological functions of lncRNA PVT1 and STAT5B. Quantitative real time polymerase chain reaction, Western blot, immunohistochemistry, and immunofluorescence were used to detect lncRNA PVT1 and STAT5B expression. Fluorescence in situ hybridization, RNA pull-down and RNA immunoprecipitation assays were conducted to determine the regulatory effect of lncRNA PVT1 on STAT5B. The transcriptional effect of STAT5B on lncRNA PVT1 gene was determined using luciferase reporter assay, chromatin immunoprecipitation and DNA-affinity precipitation assays. Connectivity Map analysis was used to screen anticancer drugs. RESULTS: LncRNA PVT1 and STAT5B enhance the expression of each other and promote the malignant phenotypes in BC, including cell viability and invasion. lncRNA PVT1 stabilizes STAT5B by decreasing ubiquitination, enhances STAT5B phosphorylation, and promotes the translocation to the nucleus of STAT5B to trigger further carcinogenesis activities. In the nucleus, STAT5B activates the transcription of lncRNA PVT1 by binding directly to its promoter region, leading to a positive feedback. Tanespimycin effectively abated the oncogenic effect. CONCLUSIONS: We first identified the lncRNA PVT1/STAT5B positive feedback loop for bladder carcinogenesis, and found a potentially effective drug for BC.	bladder
Second malignant tumors and non-tumor causes of death for patients with localized and regional kidney cancer after diagnosis.	BACKGROUND: To evaluate the second malignant tumors (SMTs) and non-tumor causes of death among patients diagnosed with localized and regional kidney cancer. METHODS: Patients diagnosed with kidney cancer between 2000 and 2017 in the Surveillance, Epidemiology, and End Results (SEER) program database were identified. All causes of death for patients during the follow-up and standardized mortality ratio (SMR) were analyzed. RESULT: 113,734 patients with localized kidney cancer with 30,390 cases of death were analyzed. 60.4% of the death cases were due to non-tumor caused and 23.6% were second malignant tumors (SMTs). Main SMTs included cancers of lung and bronchus [n = 1,283, SMR: 1.00 (0.95-1.06)] and pancreas [n = 393, SMR: 1.27 (1.15-1.41)]. Causes of death for non-tumor mainly included heart diseases [n = 6,161, SMR: 1.25 (1.21-1.28)] and chronic obstructive pulmonary disease (COPD) [n = 1,185, SMR: 0.99 (0.94-1.05)]. 14,437 of 29,602 patients with regional kidney cancer died. 14.6% of all deaths were due to SMTs and 23.6% due to non-tumor causes. Main SMTs contained bladder cancer [n = 371, SMR: 10.90 (9.81-12.06)] and lung and bronchus cancer [n = 346, SMR: 1.21 (1.08-1.34)]. The main non-tumor death was heart disease [n = 1,424, SMR: 1.26 (1.2-1.33)]. When stratified by pathological types, patients with clear cell renal cell carcinoma (RCC) did not have increased mortality risks of bladder cancer and lung cancer but patients with non-clear cell RCC did. CONCLUSION: SMTs and non-tumor diseases including lung and bronchus cancer, bladder cancer, pancreas cancer, diseases of heart, COPD, and cerebrovascular diseases are the leading causes of death besides kidney cancer and should be paid more attention during patients' survival period.	bladder
A phase Ib/II dose expansion study of subcutaneous sasanlimab in patients with locally advanced or metastatic non-small-cell lung cancer and urothelial carcinoma.	BACKGROUND: Sasanlimab is an antibody to the programmed cell death protein 1 receptor. We report updated data of subcutaneous sasanlimab in non-small-cell lung cancer (NSCLC) and urothelial carcinoma dose expansion cohorts from a first-in-human phase Ib/II study. PATIENTS AND METHODS: Patients were ≥18 years of age with NSCLC or urothelial carcinoma, and no prior immunotherapies, who progressed on or were intolerant to systemic therapy, or for whom systemic therapy was refused or unavailable. Patients received subcutaneous sasanlimab at 300 mg every 4 weeks (q4w). Primary objectives were to evaluate safety, tolerability, and clinical efficacy by objective response rate (ORR). RESULTS: Sixty-eight and 38 patients with NSCLC and urothelial carcinoma, respectively, received subcutaneous sasanlimab. Overall, sasanlimab was well tolerated; 13.2% of patients experienced grade ≥3 treatment-related adverse events. Confirmed ORR was 16.4% and 18.4% in the NSCLC and urothelial carcinoma cohorts, respectively. ORR was generally higher in patients with high programmed death-ligand 1 (PD-L1) expression (≥25%) and high tumor mutational burden (TMB; >75%). In the NSCLC and urothelial carcinoma cohorts, median progression-free survival (PFS) was 3.7 and 2.9 months, respectively; corresponding median overall survival (OS) was 14.7 and 10.9 months. Overall, longer median PFS and OS correlated with high PD-L1 expression and high TMB. Longer median PFS and OS were also associated with T-cell inflamed gene signature in the urothelial carcinoma cohort. CONCLUSIONS: Subcutaneous sasanlimab at 300 mg q4w was well tolerated with promising clinical efficacy observed. Phase II and III clinical trials of sasanlimab are ongoing to validate clinical benefit. Subcutaneous sasanlimab may be a potential treatment option for patients with NSCLC or urothelial carcinoma.	bladder
Phase II study of a trastuzumab biosimilar in combination with paclitaxel for HER2-positive recurrent or metastatic urothelial carcinoma: KCSG GU18-18.	BACKGROUND: Human epidermal growth factor receptor 2 (HER2) is a widely explored therapeutic target in solid tumors. We evaluated the efficacy and safety of trastuzumab-pkrb, a biosimilar of trastuzumab, in combination with paclitaxel, in HER2-positive recurrent or metastatic urothelial carcinoma (UC). PATIENTS AND METHODS: We enrolled 27 patients; they were administered a loading dose of 8 mg/kg trastuzumab-pkrb on day 1, followed by 6 mg/kg and 175 mg/m(2) paclitaxel on day 1 every 3 weeks, intravenously. All patients received six cycles of the combination treatment and continued to receive trastuzumab-pkrb maintenance until disease progression, unacceptable toxicity, or for up to 2 years. HER2 positivity (based on immunohistochemistry analysis) was determined according to the 2013 American Society of Clinical Oncology /College of American Pathologists HER2 testing guidelines. The primary endpoint was objective response rate (ORR); the secondary endpoints were overall survival (OS), progression-free survival (PFS), and safety. RESULTS: Twenty-six patients were evaluated via primary endpoint analysis. The ORR was 48.1% (1 complete and 12 partial responses) and the duration of response was 6.9 months [95% confidence interval (CI) 4.4-9.3 months]. With a median follow-up of 10.5 months, the median PFS and OS were 8.4 months (95% CI 6.2-8.8 months) and 13.5 months (95% CI 9.8 months-not reached), respectively. The most common treatment-related adverse event (TRAE) of any grade was peripheral neuropathy (88.9%). The most common grade 3/4 TRAEs were neutropenia (25.9%), thrombocytopenia (7.4%), and anemia (7.4%). CONCLUSIONS: Trastuzumab-pkrb plus paclitaxel demonstrates promising efficacy with manageable toxicity profiles in patients with HER2-positive recurrent or metastatic UC.	bladder
Antisense lncRNA-RP11-498C9.13 promotes bladder cancer progression by enhancing reactive oxygen species-induced mitophagy.	BACKGROUND: Urinary system's most prevalent malignant tumor is bladder cancer. The enzyme pyrroline-5-carboxylate reductase 1 (PYCR1) has pro-tumorigenic characteristics. In the present study, the upstream and downstream regulatory mechanisms of PYCR1 in bladder cancer were investigated. METHODS: The relationship between the expression of PYCR1 in bladder cancer and its prognosis was analyzed using a bioinformatics technique. Plasmid transfection and small interfering RNA were utilized to overexpress and silence genes, respectively. Utilizing MTT, colony formation, EdU, and transwell assays, the proliferation and invasiveness of bladder cancer cells were evaluated. Employing an RNA pull-down experiment and RNA immunoprecipitation, the relationship between RNAs was analyzed. Fluorescence in situ hybridization, immunohistochemistry, and western blotting were used to detect protein expression and localization. Flow cytometry was used to identify reactive species (ROS) expression in cells. Mitophagy was detected using immunofluorescence. RESULTS: PYCR1 was highly expressed in bladder cancer tissue and was related with a poor prognosis for the patient. By binding to PYCR1, the antisense RNA lncRNA-RP11-498C9.13 prevented the degradation of PYCR1 and promoted its production. Down-regulation of lncRNA-RP11-498C9.13 and PYCR1 inhibited the proliferation and invasiveness of bladder cancer cells and decreased tumorigenesis. In addition, it was found that the lncRNA-RP11-498C9.13/PYCR1 axis promoted ROS generation and induced mitophagy in bladder cancer cells. CONCLUSIONS: We demonstrated that lncRNA-RP11-498C9.13 promoted bladder cancer tumorigenesis by stabilizing the mRNA of PYCR1 and promoted ROS-induced mitophagy. The lncRNA-RP11-498C9.13/PYCR1/mitophagy axis was anticipated to be a significant therapeutic target for bladder cancer.	bladder
Urinary bladder hemangiosarcoma in a cat treated with partial cystectomy and adjuvant metronomic cyclophosphamide and thalidomide.	Visceral hemangiosarcomas (HSA) are rare in cats and typically associated with aggressive biologic behavior and poor prognosis. A 4-year-old male neutered domestic shorthair cat was presented with a 3-month history of hematuria and stranguria; ultrasonography identified a large bladder mass. Complete excision was achieved by partial cystectomy. Histopathology and immunohistochemistry for von Willebrand factor confirmed HSA. The cat was treated using adjuvant cyclophosphamide, thalidomide, and meloxicam for 8 months. Abdominal ultrasonography repeated at 2 months and computed tomography repeated at 5 and 19 months after diagnosis showed no evidence of local recurrence or metastasis. The cat was alive at last follow-up (896 days). Although the cat described in this report experienced a more favorable prognosis compared to other visceral HSA locations, additional cases are needed to further understand the biological behavior of bladder HSAs and guide treatment decisions.	bladder
Nationwide analysis of survival after radical cystectomy for bladder cancer in Finland.	BACKGROUND: Population-based survival results after radical cystectomy (RC) are limited. Our objective was to report short and long-term survival results after RC for bladder cancer from Finland in a population-based setting. MATERIALS AND METHODS: The Finnish National Cystectomy Database containing retrospectively collected essential RC data covering the years 2005-2017 was combined with the survival data from the Finnish Cancer Registry. Kaplan-Meier plots were used to estimate survival and the survival graphs were illustrated according to the final pathological staging. Centers were divided according to operational volume, and the results were then compared using Pearsons's Chi-squared test. RESULTS: A total of 2047 patients were included in the study. 30-, and 90-day mortality was 1.3%, and 3.8%, respectively. The OS of the entire RC population at 5- and 10 years was 66% and 55%, and CSS was 74% and 72%, respectively. Center volume did not significantly associate with surgical mortality or long-term survival. The 5- and 10-year OS according to pT-category was 87% and 74% for pT0, 85% and 69% for pTa-pTis-pT1, 70% and 58% for pT2, 50% and 42% for pT3 and 41% and 30% for pT4. The corresponding 5- and 10-year CSS rates were 96% and 93% for pT0, 91% and 90% for pTa-pTis-pT1, 78% and 75% for pT2, 56% and 55% for pT3 and 47% and 44% for pT4. The 5- and 10-year OS rates in patients with no lymph node metastases (pN-) were 74% and 62%, and CSS 82% and 80%, respectively. If lymph nodes were positive (pN+), the corresponding OS rates were 44% and 34% and CSS 49% and 48%, respectively. CONCLUSION: RC survival results have improved in contemporary series and are associated with the pTNM-status. The nationwide results from Finland demonstrate outcome comparable to high volume single-center series.	bladder
The perioperative and long-term outcomes of patients with variant histology bladder cancer undergoing radical cystectomy: A propensity score-matched analysis with pure urothelial carcinoma.	OBJECTIVES: To assess the perioperative and long-term outcomes after open radical cystectomy in patients with histological variants versus pure urothelial carcinoma. METHODS: Patients with a variant histology carcinoma of the urinary bladder were matched through a propensity score analysis with those with pure urothelial carcinoma on a 1:3 ratio. The two groups were compared in terms of perioperative and long-term morbidity and mortality. RESULTS: Overall, 148 individuals were included in the present retrospective study (37 with variant histology and 111 with pure urothelial carcinoma). A total of 107 (72.3%) individuals presented at least one perioperative complication based on the Clavien-Dindo classification. This proportion was similar between patients with urothelial versus variant histology carcinoma (P = .22). In the long term, the number of patients with clinically significant incisional hernia requiring surgery [14 (12.7%) vs 3 (8.3%), P = .68], uretero-intestinal/uretero-cutaneous strictures or any other complication related to the applied urinary diversion [15 (13.6%) vs 7 (19.4%), P = .56], as well as the number of patients presenting with septicemia [17 (15.5%) vs 10 (27.8%), P = .16] or with urinary tract obstruction [12 (10.9%) vs 4 (11.1%), P > .99] at follow-up did not differ between urothelial versus variant histology carcinoma. The survival analysis with Kaplan-Meier curves and the univariate Cox regression model suggested that the risk of death from any cause was increased in patients with variant compared to pure urothelial histology (log-rank test = 0.045, hazard ratio: 1.7, 95% confidence interval: 1.01-2.87, P = .047). CONCLUSIONS: Perioperative morbidity and mortality are comparable in patients with variant histology versus pure urothelial carcinoma.	bladder
Targeting bladder cancer: A sex sensitive perspective in mutations and outcomes.	The incidence of bladder cancer (BC) is more common in males, however, the clinical outcome for females tends to be more unfavorable, as demonstrated by a 21% increase in mortality compared to males within two years of diagnosis. While it was previously believed that the differences in outcome were solely the result of differences in sex chromosomes and hormones, it is now acknowledged that a more intricate interplay of factors is at play. By acquiring a more comprehensive understanding of these sex-specific effects, future efforts in precision medicine can be customized to an individual's biological sex. This narrative review aims to summarize our knowledge of the molecular classification of sex differences in BC by compiling the existing evidence on genetic disparities between males and females and evaluating these disparities in both noninvasive bladder cancer (NMIBC) and muscle invasive bladder cancer (MIBC). Our findings emphasize the significance of considering sex as a factor in future clinical trials and registry studies due to established differences in immune composition, molecular profiling, and genetic mutations between males and females. Further investigation into the molecular processes involved in the evasion or resistance of immune-based therapies, such as Bacillus Calmette-Guérin and other immunotherapies, is essential to identify markers of response or resistance that vary between male and female patients. This will aid in optimizing treatment and promoting equitable outcomes, particularly in NMIBC cases.	bladder
Comparison between different neoadjuvant chemotherapy regimens and local therapy alone for bladder cancer: a systematic review and network meta-analysis of oncologic outcomes.	PURPOSE: The present systematic review and network meta-analysis (NMA) compared the current different neoadjuvant chemotherapy (NAC) regimes for bladder cancer patients to rank them. METHODS: We used the Bayesian approach in NMA of six different therapy regimens cisplatin, cisplatin/doxorubicin, (gemcitabine/cisplatin) GC, cisplatin/methotrexate, methotrexate, cisplatin, and vinblastine (MCV) and (MVAC) compared to locoregional treatment. RESULTS: Fifteen studies comprised 4276 patients who met the eligibility criteria. Six different regimes were not significantly associated with a lower likelihood of overall mortality rate compared to local treatment alone. In progression-free survival (PFS) rates, cisplatin, GC, cisplatin/methotrexate, MCV and MVAC were not significantly associated with a higher likelihood of PFS rate compared to locoregional treatment alone. In local control outcome, MCV, MVAC, GC and cisplatin/methotrexate were not significantly associated with a higher likelihood of local control rate versus locoregional treatment alone. Nevertheless, based on the analyses of the treatment ranking according to SUCRA, it was highly likely that MVAC with high certainty of results appeared as the most effective approach in terms of mortality, PFS and local control rates. GC and cisplatin/doxorubicin with low certainty of results was found to be the best second options. CONCLUSION: No significant differences were observed in mortality, progression-free survival and local control rates before and after adjusting the type of definitive treatment in any of the six study arms. However, MVAC was found to be the most effective regimen with high certainty, while cisplatin alone and cisplatin/methotrexate should not be recommended as a neoadjuvant chemotherapy regime.	bladder
Enhancing bladder cancer care through the multidisciplinary clinic approach.	INTRODUCTION: To report the impact of our 25-year multidisciplinary care delivery model experience on patients with muscle invasive bladder cancer treated at our National Cancer Institute (NCI)-designated Sidney Kimmel Cancer Center at Jefferson University. To our knowledge, our multidisciplinary genitourinary cancer clinic (MDC) is the longest continuously operating center of its kind at an NCI Cancer Center in the United States. MATERIALS AND METHODS: We selected a recent group of patients with cT2-4 N0-1 M0 bladder cancer seen in the Sidney Kimmel Cancer Center Genitourinary Oncology MDC from January 2016 to September 2019. These patients were identified retrospectively. SEER-18 (Surveillance, Epidemiology, and End Results) database, November 2019 submission was queried to obtain patients with similarly staged disease diagnosed between 2015 and 2017. Completion rates of radical cystectomy, use of neoadjuvant therapies, and survival outcomes were compared between the two cohorts. RESULTS: Ninety-one patients from the MDC form this time period were identified; 65.9% underwent radical cystectomy and 71.8% received neoadjuvant therapy in the form of chemotherapy, immune checkpoint inhibition or a combination of the two - higher than reported national trends for neoadjuvant therapies. Progression of disease was seen in 24.2% of patients. A total of 8675 patients met inclusion criteria in the SEER database. Rates of radical cystectomy were significantly higher in MCD patients when compared to SEER derived data (65.9% vs. 37.7%, p =< 0.001). MCD patients had significantly better cancer-specific survival (mean 20.4 vs. 18.3 months p = 0.028, median survival not reached). CONCLUSION: Our long term experience caring for patients with genitourinary malignancies such as bladder cancer in a uniform multidisciplinary team results in a high utilization of neoadjuvant therapies. When compared to a contemporary SEER-derived cohort, multidisciplinary patients were more likely to undergo radical cystectomy and had longer cancer-specific survival.	bladder
